Who were the Puritans, and why should Christians still read them today?

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Stephen Yuille, professor of church history at Southwestern Baptist Theological Seminary and director of Puritan publishing at Reformation Heritage Books, to explore the enduring relevance of the Puritans for the Christian life.

Dr. Yuille explains who the Puritans really were, addresses common misconceptions about their history, and discusses their remarkable ability to unite sound theology with heartfelt devotion. At the center of their teaching was a conviction that Christianity is more than simply knowing the truth—it is knowing God personally, delighting in Christ, and allowing biblical truth to shape every part of life.

Dr. Yuille offers practical recommendations for those beginning to read the Puritans, including several essential works for pastors and everyday Christians.

What calls a person to preach the gospel or carry it to the nations? And how can the church help prepare them?

In this episode of the Unashamed Truth podcast, Grant Castleberry sits down with Ian Hamilton to discuss his conversion in Glasgow, his call to pastoral ministry, and the vital role of the local church in discerning and confirming that call. Drawing on decades as a pastor and seminary professor, Hamilton explains why theological training must shape a minister’s character as well as his mind.

The conversation then turns to world missions. Hamilton shares how missionary biographies and his work with Radius International have deepened his concern for unreached peoples. His central appeal is to see the glory of Christ: the Savior is worthy of being known, loved, and worshiped among all nations.

Whether you are considering ministry or seeking to strengthen your church’s commitment to missions, this conversation offers biblical counsel and encouragement.

In this episode of the Unashamed Truth Podcast, Grant Castleberry sits down with Andy Young, pastor of Oxford Presbyterian Church in Oxford, England, to discuss reaching and discipling a new generation of young men.

Andy shares his journey to Christ, his introduction to the doctrines of grace, and the work God is doing through a Reformed church in the heart of one of the world’s most influential university cities. He also reflects on what young people are searching for today: authenticity, substance, transcendence, community, and beauty.

Grant and Andy discuss biblical masculinity, the importance of strong preaching and sound doctrine, and why discipleship requires patient, personal investment. Rather than lowering the bar to reach young men, Andy argues that the church should offer them something deeper: the truth of Scripture, the glory of Christ, meaningful Christian community, and a vision of manhood shaped by courage, humility, conviction, and sacrifice.
